Manganese Violet (CI 77742)

What it is

Identified on ingredient lists by Color Index number CI 77742, manganese violet is an inorganic purple mineral pigment added to cosmetics strictly for color and tone adjustment. It does not offer hydration, exfoliation, or active skincare benefits. Formulators include it in decorative cosmetics to create purple shades and balance color tones across diverse makeup products.

In the United States, color additives must be permitted for their intended use. FDA tables identify which additives may be used in different types of cosmetics, including products for the eye area and lips, and whether a color is subject to batch certification. FDA lists manganese violet as permitted for the eye area and exempt from batch certification. The CI number and the pigment name are alternate ways to identify the colorant; checking both can help when you compare labels.

What it does

• Provides violet color. It supplies pigment that contributes to the product’s shade.
• Supports shade matching. A formulator can use it alone or with other colorants to adjust a finished color.
• Identifies a regulated colorant. The CI number helps distinguish this pigment from other violet color additives.

Who it suits

Manganese violet is a colorant rather than an active aimed at a skin type. It matters mainly when comparing shades or checking a known sensitivity. Whether the overall product feels comfortable depends on the rest of the formula, including binders, waxes, fragrance, and preservatives.

In the United States, some color additives require batch certification and others are exempt. FDA lists manganese violet for the eye area and general cosmetic use. That regulatory fact does not predict an individual’s sensitivity. A dermatologist can help assess recurring reactions.

What to pair it with, and what not to

Manganese violet does not need to be paired with a skincare active. It is part of the color blend in a finished cosmetic. Choose makeup based on the shade, formula, and intended area of use, and follow the package directions.
